Hello,I updated my Joomla Installation to 3.5.0 - Post by email was working fine before, now not anymore ...The cronjob displays message:"Error displaying the error page: Application Instantiation Error: Failed tostart the session because headers have already been sent by "" at line 0."I have no Idea where to start to look for the problem - please help!Thank's,Tom

This is nothing that comes from PostbyEmail, is due on your server configuration. So, here are some questions to start:- Are you reading configuration guide: http://3dwebdesign.org/forum/post-by-email-pro-t743- What happened when you configure your emal box in Post by email and are settings right (take attention on port)?- And after this what happened when you click on button import?- What are your settings?
